Objective: To evaluate whether 3D magnetic resonance myelography (MRmyelography) using fat-suppressed-three dimensional coherent oscillatory state acquisition for the manipulation of the image contrast (FS 3D-COSMIC) sequence has additional diagnostic value in the diagnosis of lumbar canal stenosis. Materials and Methods: The patient population consisted of 30 patients who were seen for the diagnosis of lumbar canal stenosis. The lumbar segments were divided into 15 groups, from L1-L2 to L5-S1
